The second-generation Cologne V6 was introduced in 1974. It displaced 2.8 L; 170.4 cu in (2,792 cc) with a bore and stroke of 93.03 mm × 68.5 mm (3.66 in × 2.70 in), and used a geared camshaft design. While based on the 2.6, the larger bore necessitated a different block. [2]
In some older engines (such as the Chevrolet Gen-2 "Stovebolt" inline-six, the GMC straight-6 engine, the Buick Straight-eight, and the Chrysler "Slant 6") the bore pitch is additionally extended to allow more material between the main bearing webs in the block. For example, in an L6 the first pair (#1 & 2), center pair (#3 & 4), and rear pair ...
A desaxe engine, is one in which each cylinder is positioned with its exact center (the bore axis) slightly offset from the center line of the crankshaft. "Désaxé", in French, means "unbalanced". Desaxe engines are usually automotive, but the term can also apply to steam engines. An animation of a Scuderi Split Cycle Engine.
The 301.6-cubic-inch (4.9 L) GMC inline six was produced from 1952 to 1960, when it was replaced by the V6. It has a square bore/stroke ratio of 4 by 4 inches (101.6 mm × 101.6 mm). This is the largest raised-deck engine. It was originally designed for the GMC military M135 and M211.
Bore and stroke size is 3.552 in × 4.165 in (90.2 mm × 105.8 mm), identical to the 5.4 L V8. Both 2-valve and 3-valve versions have been produced. The 6.8 L uses a split-pin crank with 72° firing intervals and a balance shaft gear driven by the left camshaft to quell vibrations inherent to a 90° bank angle V10 engine. The engine's firing ...
Both an increased stroke or bore cause an increased secondary vibration; a larger stroke increases the difference in acceleration and a larger bore increases the mass of the pistons. The Lanchester design of balance shaft systems was refined with the Mitsubishi Astron 80, an inline-four car engine introduced in 1975. This engine was the first ...
